problem with scrubber

[Punisher]

I have a problem with scrubber, I have it set since march but it does not grow it looks like it shows in the pictures. On one side I have a saving light bulb of 20W and on the other side two led of 10w..eight red ones and a blue one for growth. I think my problem is because I did not scrape the mesh right. In my fish tank I have alga on the glass and on some rocks. I will appreciate your comments.

It looks like it needs more light. If it does not grow more in the next 10 days, move the light more near the screen, and keep the lights on for 22 hours.
